Interface Summary

Interface	Description
HystrixCircuitBreaker	Circuit-breaker logic that is hooked into HystrixCommand execution and will stop allowing executions if failures have gone past the defined threshold.
HystrixCollapser.CollapsedRequest<ResponseType,RequestArgumentType>	A request argument RequestArgumentType that was collapsed for batch processing and needs a response ResponseType set on it by the executeBatch implementation.
HystrixCollapserKey	A key to represent a HystrixCollapser for monitoring, circuit-breakers, metrics publishing, caching and other such uses.
HystrixCommandGroupKey	A group name for a HystrixCommand.
HystrixCommandKey	A key to represent a HystrixCommand for monitoring, circuit-breakers, metrics publishing, caching and other such uses.
HystrixExecutable<R>	Common interface for executables (HystrixCommand and HystrixCollapser) so client code can treat them the same and combine in typed collections if desired.
HystrixInvokable<R>	Marker interface for Hystrix commands that can be invoked.
HystrixInvokableInfo<R>
HystrixObservable<R>	Common interface for executables that implement the Observable methods HystrixObservable.observe() and HystrixObservable.toObservable() so client code can treat them the same and combine in typed collections if desired.
HystrixThreadPool	ThreadPool used to executed HystrixCommand.run() on separate threads when configured to do so with HystrixCommandProperties.executionIsolationStrategy().
HystrixThreadPoolKey	A key to represent a HystrixThreadPool for monitoring, metrics publishing, caching and other such uses.

Class Summary

Class	Description
ExecutionResult	Immutable holder class for the status of command execution.
ExecutionResult.EventCounts
Hystrix	Lifecycle management of Hystrix.
HystrixCachedObservable<R>
HystrixCircuitBreaker.Factory
HystrixCircuitBreaker.HystrixCircuitBreakerImpl	The default production implementation of HystrixCircuitBreaker.
HystrixCircuitBreaker.NoOpCircuitBreaker	An implementation of the circuit breaker that does nothing.
HystrixCollapser<BatchReturnType,ResponseType,RequestArgumentType>	Collapse multiple requests into a single HystrixCommand execution based on a time window and optionally a max batch size.
HystrixCollapser.Setter	Fluent interface for arguments to the HystrixCollapser constructor.
HystrixCollapserKey.Factory
HystrixCollapserMetrics	Used by HystrixCollapser to record metrics.
HystrixCollapserProperties	Properties for instances of HystrixCollapser.
HystrixCollapserProperties.Setter	Fluent interface that allows chained setting of properties that can be passed into a HystrixCollapser constructor to inject instance specific property overrides.
HystrixCommand<R>	Used to wrap code that will execute potentially risky functionality (typically meaning a service call over the network) with fault and latency tolerance, statistics and performance metrics capture, circuit breaker and bulkhead functionality.
HystrixCommand.Setter	Fluent interface for arguments to the HystrixCommand constructor.
HystrixCommandGroupKey.Factory
HystrixCommandKey.Factory
HystrixCommandMetrics	Used by HystrixCommand to record metrics.
HystrixCommandMetrics.HealthCounts	Number of requests during rolling window.
HystrixCommandProperties	Properties for instances of HystrixCommand.
HystrixCommandProperties.Setter	Fluent interface that allows chained setting of properties that can be passed into a HystrixCommand constructor to inject instance specific property overrides.
HystrixCommandResponseFromCache<R>
HystrixCounters	Class with global statistics on Hystrix runtime behavior.
HystrixMetrics	Abstract base class for Hystrix metrics
HystrixObservableCollapser<K,BatchReturnType,ResponseType,RequestArgumentType>	Collapse multiple requests into a single HystrixCommand execution based on a time window and optionally a max batch size.
HystrixObservableCollapser.Setter	Fluent interface for arguments to the HystrixObservableCollapser constructor.
HystrixObservableCommand<R>	Used to wrap code that will execute potentially risky functionality (typically meaning a service call over the network) with fault and latency tolerance, statistics and performance metrics capture, circuit breaker and bulkhead functionality.
HystrixObservableCommand.Setter	Fluent interface for arguments to the HystrixObservableCommand constructor.
HystrixRequestCache	Cache that is scoped to the current request as managed by HystrixRequestVariableDefault.
HystrixRequestLog	Log of HystrixCommand executions and events during the current request.
HystrixThreadPool.Factory
HystrixThreadPool.HystrixThreadPoolDefault
HystrixThreadPoolKey.Factory
HystrixThreadPoolMetrics	Used by HystrixThreadPool to record metrics.
HystrixThreadPoolProperties	Properties for instances of HystrixThreadPool.
HystrixThreadPoolProperties.Setter	Fluent interface that allows chained setting of properties that can be passed into a HystrixThreadPool via a HystrixCommand constructor to inject instance specific property overrides.
HystrixTimerThreadPoolProperties	Properties for Hystrix timer thread pool.
HystrixTimerThreadPoolProperties.Setter	Fluent interface that allows chained setting of properties.
